To all who'm it "may concern:

Be it knmvnthat 1, GEORGE W. Gonnns; a citizen of the United States, residing at Phil adel hia, county of Philadelphia, and State of ennsylvania, have invented acertain new" and useful Improvement in Oilers for Gas-Engines and the Like, of which the following is a specification.

My invention relates to a new and useful improvement in oilers for gas-engines and the like, and has for its object to provide a Simple and effective arrangement. by which the wrist-pin and trunk-cylinder may be 7, properly lubricated while the engine is in oporation and to also provide for the proper lubrication of the hearing-surfaces between the cylinder and piston.

.With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth p and then specifically designated claims.

i In order that those skilled in the art to which this invention appertains may under- 4 are formed the grooves D for receiving Oll stand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawings, forming a part of this specification, 1n

w q Figure 1 is a longitudinal section of a porvtion of a cylinder, showing the piston therei11,'the, iston being partially broken away and sectioned so as to show the means of conveying the oil to the wrist-pin; Fig. 2, an exterior view of the piston looking downward. :rf'In carrying out my invention as here embodied, A re resents the cylinder, and B the 'isto'n fitte to slide therein. as fitted thereto the usual packing-rings C, and around the trunk portion of the pistoii from the; cross groove or channel E and conveying said oilback and forth within the cylinder.

F is an oil-cup connected by the pipe G to the interiorof the cylinder, so as to feed oil to the'cha'nnel E, from whence it will be fed to the grooves D, as will be readily understood. H also represents an oil-cup, which is-attached to the cylinder and is provided with the feed-pipe I, the latter having at its lower end a iced-wick J, which permits a sinall quantity of oil to percolate there through and accumulate upon the lower end thereof for the purpose hereinafter set forth Specification ofiLetters Eatent.

This piston Patente K. is a pipe leading iroii'rl piston B and extending wi the drip-pipe L, the lei-Vere contracte il and. located immediately above the head of the connecting-rod M, andin said to the wrist- \in while the engine is mopration, sons to reep it properly lubricated;

In order to prevent the piston from hamniering by the rings C forming a shoulder in the cylinder at the end of the stroke of the piston, 1 form a groove P around the interior of the cylinder atthe point where the for- Ward ring upon the piston will just overlap said groove at the iorward stroke of said piston, thus forming a clearance, and I also pre for to form a groove Q around the piston behind the outer ring, so as to convey oil to the rear portion of the cylinder.

Of course I do not wish to be limited to the use of my improvement in connection with any particular style of engine, as it is adapted for use in any engine using a trunk-piston.

Having thus fully described my invention, what I claim as new and useful is- 1. In combination with an engine oi the character described, a piston having a series of grooves formed around its outer circumference, a longitudinal channel connecting said grooves and means for supplying oil to said channel, as specified.

-2. In combination with an engine of the character described, piston having a series of grooves formed around its outer circumference, a longitudinal channel connecting said grooves, an oil-cup adapted to feed oil to said channel, a second oil-cup, a fecd-pipe-leading downward from the last-named. oil-cup, a feeding-wick carried by the lower end of said feed-pipe, a pipe K carried by the piston and adapted to receive oil from the Wick, a drippipe L to which the pipe K is secured and a piston-rod head having a recess formed therein for catching the oil falling from the drip-pipe, as specified.

3. In combination with sin-engine of the character described, a hollow piston, a drippipe, secured Within said piston, the. outlet from said pipe being located immediately above a recess formed in the piston-rod head, apipe K secured to the drip-pipe its outer end projecting beyond the piston and turned upward, at feed-pipe I having a feed-Wick J secured in its lower end adapted to deliver oil to the pipe K at each outward stroke of the I for supplying oil thereto, as specified.

In testimony whereof I have'hereuntoaffixed my signature in the presence of two subscribing Witnesses v I GEORGE W. GOEHNS.
